To the OP, this sounds like a good lead:
try paeco performance,its a small company that offers a wide variety of performance parts including weber carbs.its been a while since i have done bussiness with them but i think they are still around
Chilsam, ram air systems do not affect air intake temperature, and intercoolers only directly affect intake air temperature before it enters the throttle body. In the preceding discussions, I was referring mostly to the temperature of the intake manifold itself, and the effect it has on intake air temperature. Heat is conducted into the manifold from the head, and convected into the manifold through the hot air present in the engine bay. Drive any car in stop and go traffic and put your hand on the intake manifold. Regardless of whether the engine is air or water cooled, the manifold has coolant circulated through it or not, or the engine is boosted or naturally aspirated, the manifold will be significantly hotter than ambient air, and most often too hot for the average human to touch for any extended period of time without significant discomfort.
You are 100% correct, Chilsam, in stating that air becomes less dense with heat, thus reducing it's potential for making power. The sole purpose of Ram air, however, is to accept air from an area where pressure is higher than atmospheric conditions, creating a slight supercharging effect. Your average intercooler, including all intercoolers that I know of on stock production turbo and/or supercharged cars is air to air, meaning that they will never be able to reduce the temperature of the air to less than ambient air temperature. This means that any air to air intercooler can only negate the heating effects on the intake air temperature of a turbo or supercharger. It has only an indirect effect on the heat absorbed into the intake air charge from the intake manifold.
There are ways to cool the intake air charge below ambient air temperature, but they require a cold medium to absorb heat, which must be somehow replenished, be it ice, water/alcohol injection, or otherwise. Such technologies can, however, reduce air intake charge temperature vastly, even on a naturally aspirated engine. Hell, a carburetor has something of a cooling effect, just not enough to significantly cool a big chunk of cast aluminum containing hot coolant and being constantly heated by your engine. Bottom line is, your intake manifold gets hot, regardless of design or function, and the heat transfers into the air entering your engine.
The main question now is, can we completely eliminate the flow of coolant through the intake manifold of a 2.3 or 2.0, without adversely affecting the functionality of the cooling system.
If this post does not make sense in any way, is irrelevant to any/all preceding discussion, and/or is just too long, I hereby direct all liability to Latrobe Brewing Co., St. Louis, Mo.
